Jamie went to dinner. Her meal cost $12.40. She wanted to leave a 15%
tip. How much was her tip?

Hi there! The answer is $1.86. Hope this helps! c:

Step-by-step explanation:

First, convert 15% to a decimal.

15% / 100 = 0.15

Then, multiply.

0.15 * 12.40 = $1.86

Since 15% of 12.40 is $1.86, then Jamie left a $1.86 tip.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
